Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when registering authentication information used to permit entry into a facility such as an apartment, it is common to use a face image in which a person is not wearing a shielding object (for example, a mask) that shields a part of the face. Therefore, when registering authentication information, it is necessary to remove the shielding object that shields a part of the face.

[0005] In view of the above reasons, the present disclosure is made, and an object thereof is to provide a registration system, a registration method, and a program that can facilitate the registration of authentication information.

Means for Solving the Problems

[0006] A registration system according to one aspect of the present disclosure is a registration system for registering authentication information for determining whether to permit entry into a facility. The registration system includes a first acquisition unit, a second acquisition unit, a determination unit, and a registration unit. The first acquisition unit acquires face information based on a face image including a person's face. The second acquisition unit acquires attribute information regarding the person's attributes in the facility. The determination unit performs a determination process of determining whether a part of the face portion of the face image acquired by the first acquisition unit is blocked by an obscuring object. The registration unit associates a permission level based on the person's attributes with the face information and registers the face information as authentication information for determining whether to permit entry into the facility. There are multiple said permission levels. The multiple said permission levels include a predetermined permission level lower than a predetermined standard. When it is determined in the determination process that a part of the face portion is blocked by the obscuring object, the registration unit permits entry into the facility even when a part of the person's face is in a blocked state. The Register the face information as the authentication information at a predetermined permission level.

[0007] A registration method according to one aspect of the present disclosure is a registration method for registering authentication information for determining whether to permit entry into a facility. The registration method includes a first acquisition step, a second acquisition step, a determination step, and a registration step. In the first acquisition step, face information based on a face image including a person's face is acquired. In the second acquisition step, attribute information regarding the person's attributes in the facility is acquired. In the determination step, it is determined whether a part of the face portion of the face image acquired in the first acquisition step is blocked by an obscuring object. In the registration step, a permission level based on the person's attributes is associated with the face information, and the face information is registered as authentication information for determining whether to permit entry into the facility. There are multiple said permission levels. The multiple said permission levels include a predetermined permission level lower than a predetermined standard. In the registration step, when it is determined in the determination step that a part of the face portion is blocked by the obscuring object, entry into the facility is permitted even when a part of the person's face is in a blocked state. The Register the face information as the authentication information at a predetermined permission level.

[0008] A program according to an aspect of the present disclosure is a program for causing one or more processors to execute the registration method.

Modes for Carrying Out the Invention

[0011] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, the same reference numerals are assigned to elements common to each other, and redundant descriptions of the common elements may be omitted. The following embodiments are merely one of various embodiments of the present disclosure. The embodiments can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. Each drawing described in the present disclosure is a schematic diagram, and the ratio of the size and thickness of each component in each drawing does not necessarily reflect the actual dimensional ratio.

[0012] In an embodiment, in a binary comparison such as measurement data, the part where "greater than or equal to" is used may be "exceeding (greater than)". That is, in a binary comparison, whether or not the case where the two values are equal is included can be arbitrarily changed depending on the setting of a reference value or the like, so there is no technical difference between "greater than or equal to" and "exceeding". Similarly, the part where "less than or equal to" is used may be "less than".

[0013] (Embodiment) (1) Overview First, the overview of the intercom system 2 according to the present embodiment will be described with reference to FIGS. 1 to 3 and FIG. 5.

[0014] As shown in FIG. 1, the intercom system 2 according to the present embodiment is introduced into a facility 1 such as an apartment. When a person H1 (see FIG. 2) visits the facility 1, the intercom system 2 captures a face image G1 (see FIG. 5) including the face of the person H1 by the imaging unit 42 provided in the lobby intercom 4. The intercom system 2 determines whether to permit the person H1 to enter the facility 1 based on the face image G1 and the authentication information stored in advance.

[0015] As used in the present disclosure, the "facility" includes residential facilities used for residential purposes, as well as non-residential facilities such as stores (tenants), offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement arcades, hotels, inns, kindergartens, nurseries, and community centers. That is, Facility 1 may be a residential facility such as an apartment, or a non-residential facility such as an office building. Further, Facility 1 includes, for example, a facility in a form where a residential facility and a non-residential facility are mixed, such as a store on a lower floor and residential units on upper floors. As shown in FIG. 1, in the present embodiment, it is assumed that Facility 1 is an apartment building (such as an apartment) including a plurality of residential units 12. In the following description, each of the plurality of residential units 12 may be referred to as "residential unit 12".

[0016] As used in the present disclosure, the "face image" means an image (image data) obtained by imaging a range including the face of person H1, and includes videos, still images, and frame-by-frame images. In the present embodiment, a case where the face image G1 is a full-color video is exemplified. Note that the "face image" may include an image after image processing. The "image processing" may include a process of removing the background from an image including the image of person H1 and the background image, a process of changing the size of the image of person H1 included in the image, a process of changing the brightness of the image, and a process of extracting the face portion of person H1 included in the image.

[0017] As used in the present disclosure, "entry into Facility 1" means entering the internal area 15 (see FIG. 2) of the door 14 provided in Facility 1. In the present embodiment, a case where the door 14 is provided in the lobby 11 is exemplified, but there may be a plurality of doors 14 in Facility 1.

[0018] As shown in FIG. 1, the intercom system 2 according to the present embodiment includes a registration system 3 for registering authentication information for determining whether to permit entry into Facility 1.

[0019] As shown in FIG. 3, the registration system 3 of the present embodiment includes a first acquisition unit 471, a second acquisition unit 472, and a registration unit 474.

[0020] The first acquisition unit 471 acquires face information based on a face image G1 (see FIG. 5) including the face of person H1. The "face information" referred to in the present disclosure may include the face image G1 itself and information on feature amounts based on the face image G1 or the face image G1.

[0021] The second acquisition unit 472 acquires attribute information regarding the attributes of person H1 in facility 1. The "attribute" referred to in the present disclosure is a parameter for classifying person H1 based on facility 1. The "attribute" includes, for example, "resident" of dwelling unit 12 of facility 1 and "visitor" visiting facility 1. Further, the "visitor" includes "regular visitor" and "irregular visitor". The "regular visitor" includes the manager of facility 1, workers who routinely perform labor such as cleaning in facility 1, and caregivers who regularly provide care for the residents of facility 1, etc. The "irregular visitor" includes delivery operators who make deliveries to facility 1, repairers of facility 1, etc.

[0022] The registration unit 474 associates a permission level based on the attributes of person H1 with the face information and registers it as authentication information for determining whether to permit entry of the face information into facility 1. The "permission level" referred to in the present disclosure is a parameter for classifying the authentication information. In the registration system 3 of the present embodiment, there are a plurality of permission levels, and the plurality of permission levels include "permission level 1" and "permission level 2". For example, in face authentication using authentication information associated with "permission level 1", entry into facility 1 is permitted even if a part of the face of person H1 is shielded.

[0023] According to the registration system 3 of the present embodiment, a permission level based on the attributes of person H1 can be associated with the face information and registered as authentication information. For example, when the attribute of person H1 is "visitor", the registration system 3 associates a permission level ("permission level 2") that permits entry into facility 1 even if a part of the face of person H1 (visitor) is shielded by a shield such as a mask with the face information of the visitor and registers it as authentication information. Therefore, according to the registration system 3, when registering authentication information for a visitor to facility 1, for example, it is not necessary for the visitor to remove a shield such as a mask, and thus the registration of the authentication information can be facilitated.

[0024] (2) Details Hereinafter, with reference to FIGS. 1 to 6, the detailed configuration of the intercom system 2 according to the present embodiment will be described.

[0025] (2.1) Intercom system As shown in FIG. 1, the intercom system 2 of the present embodiment includes a registration system 3, a control device 5, a plurality of residential sub-units 7, a management room unit 8, and a door 14. Although details will be described later, the registration system 3 of the present embodiment includes a lobby intercom 4 and a plurality of residential master units 6. In the following description, each of the plurality of residential master units 6 may be simply referred to as the "residential master unit 6". Also, each of the plurality of residential sub-units 7 may be simply referred to as the "residential sub-unit 7".

[0026] As shown in FIG. 2, the door 14 is installed in the lobby 11 of the facility 1. The door 14 communicates with the internal area 15. The door 14 (or the electric lock provided on the door 14) is communicably connected to the lobby intercom 4 and can be controlled by the lobby intercom 4, so it is included in the components of the intercom system 2. Thereby, in the intercom system 2, the lobby intercom 4 can control the opening and closing or locking and unlocking of the door 14 in the lobby 11. That is, when the door 14 is an automatic door, the lobby intercom 4 can control the door 14 to open the door 14 that is in the closed state by default. Note that it is not essential that the door 14 is included in the configuration of the intercom system 2.

[0027] As shown in FIG. 1, the control device 5 is communicably connected to the lobby intercom 4, a plurality of residential master units 6, and the management room unit 8. The control device 5 relays communication between the lobby intercom 4, a plurality of residential master units 6, and the management room unit 8. Note that the control device 5 may be connected to a network such as the Internet outside the facility 1.

[0028] The management room machine 8 is installed in the indoor space of the management room 13 of the facility 1. Further, the management room machine 8 is communicably connected to the control device 5. The management room machine 8 is, for example, a terminal used by the manager of the facility 1 or the like.

[0029] The household sub-machine 7 is an entrance sub-machine installed outside the entrance of the household 12. The household sub-machine 7 is configured to be capable of communicating (including making a call) with the corresponding household master machine 6. Further, in the present embodiment, the household sub-machine 7 has an imaging unit (camera), and the face image G1 of the person H1 captured by the imaging unit of the household sub-machine 7 can be displayed on the household master machine 6.

[0030] (2.2) Registration system As described above, the registration system 3 of the present embodiment includes the lobby intercom 4 and the household master machine 6.

[0031] (2.2.1) Lobby intercom As shown in FIG. 2, the lobby intercom 4 is installed in the lobby 11 of the facility 1. In other words, the lobby intercom 4 is installed outside the internal area 15 of the facility 1.

[0032] As shown in FIG. 3, the lobby intercom 4 of the present embodiment includes a communication unit 41, an imaging unit 42, a call unit 43, a display unit 44, an operation unit 45, a storage unit 46, and a control unit 47.

[0033] The communication unit 41 is configured to be capable of communicating with the household master machine 6, the management room machine 8, and the door 14. Note that "capable of communicating" as used in the present disclosure means that information can be exchanged directly or indirectly via a network or a repeater or the like by an appropriate communication method of wired communication or wireless communication. Specifically, the communication unit 41 can communicate with the household master machine 6 and the management room machine 8 via the control device 5.

[0034] The imaging unit 42 includes an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge-Coupled Device) image sensor. The imaging unit 42 captures a range including the face of person H1 who attempts to operate the operation unit 45 or person H1 who operates the operation unit 45, and generates a face image G1.

[0035] The communication unit 43 includes a speaker and a microphone. The communication unit 43 of the present embodiment is configured to be able to communicate with the residential master unit 6 and the management room unit 8.

[0036] The display unit 44 is, for example, a liquid crystal display. For example, the display unit 44 is configured to display the video captured by the imaging unit 42 and also a message for the visitor. The message is, for example, a message for prompting the visitor to speak. When the lobby intercom 4 is provided with a touch panel display, the touch panel display may also serve as the display unit 44 and the operation unit 45.

[0037] The operation unit 45 is configured to receive the operation of person H1. The operation unit 45 is, for example, an input interface having a plurality of push button switches and a touch panel.

[0038] When person H1 performs a predetermined operation on the operation unit 45, the lobby intercom 4 transmits a call signal for calling the residential master unit 6 or the management room unit 8 to the residential master unit 6 or the management room unit 8. Further, the lobby intercom 4 transmits the face image G1 captured by the imaging unit 42 to the residential master unit 6 or the management room unit 8. Thereby, the face image G1 of person H1 captured by the imaging unit 42 of the lobby intercom 4 can be displayed on the residential master unit 6 or the management room unit 8.

[0039] In addition, when the lobby interphone 4 receives an entry operation on the operation unit 45, it releases (unlocks) the door 14. In other words, the person H1 can open the door 14 by performing an entry operation on the operation unit 45. Here, the "entry operation" refers to an operation performed on the operation unit 45 for the person H1 to enter the internal area 15 of the facility 1. The "entry operation" includes at least one of an operation of calling the terminal (resident master unit 6) of the visitor's destination and an operation of requesting authentication related to entry. Also, the "entry operation" includes, for example, an unlocking operation using a key inserted into a key cylinder and an operation of inputting a password for opening the door 14. For example, when a visitor calls the resident master unit 6 of the destination and the resident of the destination performs an operation of permitting opening on the resident master unit 6 after confirming the visitor, the door 14 is opened.

[0040] The storage unit 46 is composed of a device selected from an HDD (Hard Disk Drive), an SSD (Solid State Drive), a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like.

[0041] The storage unit 46 of the present embodiment stores authentication information including face information, attribute information, usage information, etc. The storage unit 46 may store the authentication information classified by attribute information, usage information, or permission level. Note that the storage unit 46 may store the face image G1 of the person H1 captured by the imaging unit 42.

[0042] The control unit 47 mainly consists of a computer system having one or more processors and one or more memories. In the control unit 47, the functions of the control unit 47 are realized by one or more processors executing a program recorded in the memory. The program may be recorded in the memory in advance, may be provided through an electric communication line such as the Internet, or may be provided by being recorded on a non-temporary recording medium such as a memory card.

[0043] The control unit 47 includes a first acquisition unit 471, a second acquisition unit 472, a third acquisition unit 473, a registration unit 474, and an authentication unit 475.

[0044] As described above, the first acquisition unit 471 acquires face information based on the face image G1 including the face of person H1. The first acquisition unit 471 of the present embodiment acquires the face information via the household master unit 6 (information terminal) provided in the household 12 (inside the facility 1) through the communication unit 41 or the like. More specifically, the first acquisition unit 471 of the present embodiment acquires, from the household master unit 6, the face information based on the face image G1 stored in a storage unit 65 (to be described later) of the household master unit 6. Since the first acquisition unit 471 acquires the face information via the household master unit 6, the lobby intercom 4 of the present embodiment can acquire, for example, the face information selected by the resident of the facility 1.

[0045] As described above, the second acquisition unit 472 acquires attribute information regarding the attributes of person H1 in the facility 1. The second acquisition unit 472 of the present embodiment acquires the attribute information from the household master unit 6 (information terminal) provided in the household 12 (inside the facility 1). Since the second acquisition unit 472 acquires the attribute information from the household master unit 6, the lobby intercom 4 of the present embodiment can acquire, for example, the attribute information selected by the resident of the facility 1.

[0046] The third acquisition unit 473 acquires the face image G1 including the face of person H1. The third acquisition unit 473 of the present embodiment acquires the face image G1 captured by the imaging unit 42 from the imaging unit 42.

[0047] As described above, the registration unit 474 registers, as authentication information for determining whether to permit entry into the facility 1 for the face information, the permission level based on the attributes of person H1 in association with the face information acquired by the first acquisition unit 471. Note that the registration unit 474 stores the authentication information in the storage unit 46.

[0048] When the attribute of person H1 is "visitor", the registration unit 474 of the present embodiment registers face information as authentication information at a permission level that allows entry into facility 1 even when a part of person H1's face is shielded. Specifically, when the acquired attribute information indicates "visitor", the registration unit 474 registers "permission level 1" in association with the face information as authentication information. As described above, "permission level 1" is a permission level that allows entry into facility 1 even when a part of person H1's face is shielded. According to the registration unit 474 of the present embodiment, when registering authentication information for a visitor, there is no need for the visitor to remove a shielding object such as a mask, so the registration of authentication information can be facilitated.

[0049] The registration unit 474 of the present embodiment can associate a plurality of permission levels with the face information for each attribute of person H1. As described above, the permission levels include "permission level 1" and "permission level 2". For example, when the attribute of person H1 is "resident", the registration unit 474 can register the face information associated with "permission level 1" and the face information associated with "permission level 2" as authentication information. According to the registration unit 474 of the present embodiment, since a plurality of permission levels can be associated with the face information for each attribute of person H1, the convenience for person H1 using facility 1 can be improved.

[0050] Note that the face information associated with "permission level 1" and the face information associated with "permission level 2" may be the same face information or different face information. However, in the present embodiment, the face information associated with "permission level 2" is based on the face image G1 in a state where a part of person H1's face is not covered by a shielding object.

[0051] Note that in this embodiment, the number of permission levels that the registration unit 474 can associate with the face information differs according to the attributes of person H1. For example, when the attribute information acquired as described above indicates "resident", the registration unit 474 in this embodiment can associate two permission levels, "permission level 1" and "permission level 2", with the face information. However, the registration unit 474 in this embodiment cannot associate "permission level 2" with the face information when the attribute information indicates, for example, "irregular visitor". In other words, the registration unit 474 can associate only "permission level 1" with the face information when the attribute information indicates, for example, "irregular visitor". That is, the number of permission levels that the registration unit 474 in this embodiment can associate with the face information differs between the case where the attribute is "resident" and the case where the attribute is "irregular visitor". Since the number of permission levels that the registration unit 474 can associate with the face information differs according to the attributes of person H1, the authentication information can be registered in a manner suitable for each attribute.

[0052] The registration unit 474 in this embodiment associates use information indicating the use according to the permission level with the face information and registers the face information as authentication information. The "use" as used in this disclosure refers to the way of using the face information (authentication information). The "use" includes at least one of a temporary use and a regular use. The "use" in this embodiment includes a temporary use and a regular use.

[0053] The face information associated with the "temporary use" is temporarily used as authentication information. The face information associated with the "temporary use" is restricted by at least one of the period of being stored as authentication information and the number of times of using the authentication information. For example, the face information associated with the "temporary use" is deleted from the storage unit 46 after 12 hours have elapsed since it was registered as authentication information.

[0054] The face information associated with the "regular use" is regularly used as authentication information. For example, the face information associated with the "regular use" may be stored in the storage unit 46 as authentication information until it is deleted by the resident or the administrator.

[0055] The registration unit 474 of the present embodiment registers, as authentication information, usage information indicating "regular usage" in association with face information only when the permission level associated with the face information is "permission level 2". In other words, when the permission level associated with the face information is "permission level 1", the registration unit 474 of the present embodiment registers, as authentication information, usage information indicating "temporary usage" in association with the face information. According to the registration unit 474 of the present embodiment, since it is possible to associate usage information according to the permission level with the face information, the security robustness can be maintained. In particular, by associating usage information indicating "temporary usage" with face information associated with a permission level lower than a predetermined standard ("permission level 1"), restrictions can be imposed on the authentication information, and the security robustness can be maintained.

[0056] The authentication unit 475 performs face authentication to determine whether to permit person H1 to enter facility 1 based on the face image G1 acquired by the third acquisition unit 473 and the authentication information. Specifically, the authentication unit 475 executes a face detection process for detecting the face portion of person H1 in the face image G1 to extract the face portion. For example, the authentication unit 475 extracts the face portion by performing image processing (pattern recognition processing) on the face image G1. The "pattern recognition processing" referred to in the present disclosure means image processing for recognizing what an object is based on the shape of the image of the object (subject) included in a certain image. As an example of this type of pattern recognition processing, there are pattern matching processing, processing for recognizing an object shown in an image using a learned model created by machine learning, and the like.

[0057] When the face portion is extracted from the face image G1, the authentication unit 475 collates (matching process) the extracted face portion with the authentication information (template data) stored in the storage unit 46. When there is authentication information in the authentication information stored in the storage unit 46 whose similarity to the extracted face portion is equal to or greater than the threshold value, the authentication unit 475 permits person H1 to enter facility 1. On the other hand, when there is no authentication information in the authentication information stored in the storage unit 46 whose similarity to the extracted face portion is equal to or greater than the threshold value, the authentication unit 475 does not permit person H1 to enter facility 1.

[0058] When, for each attribute, a plurality of permission levels are associated with the face information in the authentication unit 475 of the present embodiment, based on the face image G1 acquired by the third acquisition unit 473, one permission level is determined from among the plurality of permission levels. Then, the authentication unit 475 performs face authentication using the face information (authentication information) associated with the determined one permission level.

[0059] Specifically, when performing face authentication, the authentication unit 475 of the present embodiment executes face detection processing on the face image G1 to extract the face part, and then determines whether at least a part of the face part is blocked by an obstruction. The authentication unit 475 determines whether at least a part of the face part is blocked by an obstruction by performing pattern recognition processing on the face part.

[0060] When the face image G1 acquired by the third acquisition unit 473 is an image in which at least a part of the face of person H1 is blocked, the authentication unit 475 of the present embodiment determines, as one permission level, a permission level ( "permission level 1") that allows entry to facility 1 even when a part of the face of person H1 is blocked.

[0061] When the authentication unit 475 determines "permission level 1" as one permission level, for example, it obtains the similarity between the authentication information associated with "permission level 1" and the extracted face part. When there is authentication information in which the similarity with the extracted face part is equal to or greater than the threshold among the authentication information associated with "permission level 1", the authentication unit 475 permits person H1 to enter facility 1. On the other hand, when there is no authentication information in which the similarity with the extracted face part is equal to or greater than the threshold among the authentication information associated with "permission level 1", the authentication unit 475 does not permit person H1 to enter facility 1.

[0062] On the other hand, when the authentication unit 475 determines "permission level 1" as one permission level, for example, it does not obtain the similarity between the authentication information associated with a permission level other than "permission level 1", such as "permission level 2", and the extracted face part.

[0063] According to the authentication unit 475 of the present embodiment, face authentication is performed using face information associated with a certain permission level based on the face image G1 acquired by the third acquisition unit 473. Therefore, for example, when a part of the face of person H1 is blocked, the processing load on the authentication unit 475 can be reduced by not performing face authentication using the face information associated with "permission level 2".

[0064] (2.2.2) Resident master unit As shown in FIG. 1, the resident master unit 6 is installed in the indoor space of the residence 12.

[0065] As shown in FIG. 4, the resident master unit 6 of the present embodiment includes a communication unit 61, a call unit 62, a display unit 63, an operation unit 64, a storage unit 65, and a control unit 66.

[0066] The communication unit 61 is configured to be able to communicate with the lobby intercom 4, the resident slave unit 7, and the management room unit 8. Specifically, the communication unit 61 can communicate with the lobby intercom 4 and the management room unit 8 via the control device 5. The communication unit 61 may be configured to be able to communicate with an information terminal such as a smartphone, a tablet, or a personal computer held by a resident. The communication unit 61 of the present embodiment receives the face image G1 captured by the imaging unit 42 of the lobby intercom 4 from the lobby intercom 4.

[0067] The call unit 62 includes a speaker and a microphone. The call unit 62 of the present embodiment is configured to be able to make calls between the lobby intercom 4, the resident slave unit 7, and the management room unit 8.

[0068] The display unit 63 is, for example, a liquid crystal display. For example, the display unit 63 is configured to display the face image G1 captured by the imaging unit 42 of the lobby intercom 4 and the like. Note that the resident master unit 6 of the present embodiment includes a touch panel display, and the touch panel display serves as at least a part of the display unit 63 and the operation unit 64.

[0069] The operation unit 64 is configured to receive the operations of the residents. The operation unit 64 is, for example, an input interface having a plurality of push-button switches, a touch panel, and the like.

[0070] The storage unit 65 is composed of a device selected from an HDD, an SSD, a ROM, a RAM, an EEPROM, or the like. The storage unit 65 of the present embodiment stores the face image G1 received from the lobby interphone 4. The storage unit 65 stores, for example, a face image G1 for several seconds when the person H1 operates the operation unit 45 of the lobby interphone 4 among the face images G1 received from the lobby interphone 4.

[0071] The control unit 66 mainly includes a computer system having one or more processors and one or more memories. In the control unit 66, the functions of the control unit 66 are realized by one or more processors executing a program recorded in the memory. The program may be recorded in the memory in advance, may be provided through an electric communication line such as the Internet, or may be recorded and provided on a non-temporary recording medium such as a memory card.

[0072] The control unit 66 of the present embodiment includes a selection unit 661, a quality determination unit 662, and a notification unit 663.

[0073] The selection unit 661 allows a user such as a resident or a manager of the facility 1 to select a face image G1 (face information) to be registered as authentication information in the registration unit 474 of the lobby interphone 4, and an attribute and a use associated with the face information. In other words, the user can select face information to be registered as authentication information, and an attribute and a use associated with the face information, by operating the dwelling unit master unit 6.

[0074] For example, the user can select a face image G1 to be registered as authentication information from among the face images G1 stored in the storage unit 65 by performing a predetermined operation on the display unit 63 or the operation unit 64. Then, as shown in FIGS. 5 and 6, the selection unit 661 of the present embodiment causes the display unit 63 to display a selection screen D1 for allowing the user to select an attribute and a use to be associated with the face information. Note that FIGS. 5 and 6 show specific examples of the selection screen D1 displayed on the display unit 63, and the dashed-dotted line indicating the area and the reference signs are only shown for the purpose of explanation. Actually, these dashed-dotted lines and reference signs are not displayed on the display unit 63.

[0075] The selection screen D1 includes a first area R1 and a second area R2. The first area R1 is an area where a face image G1 including an image of the face of person H1 is displayed. The second area R2 is an area for displaying a pull-down menu M1, a pull-down menu M2, and a determination button B1. The first area R1 is arranged above the second area R2.

[0076] The pull-down menu M1 is a menu for allowing the user to select an attribute to be associated with the face information. When the pull-down menu M1 is operated by the user, a plurality of candidates for the attribute to be associated with the face information are displayed on the selection screen D1. The plurality of candidates for the attribute include "resident", "regular visitor", and "irregular visitor". The user can select an attribute to be associated with the face information from among the plurality of candidates for the attribute displayed on the selection screen D1.

[0077] The pull-down menu M2 is a menu for allowing the user to select a use to be associated with the face information. When the pull-down menu M2 is operated by the user, a plurality of candidates for the use to be associated with the face information are displayed on the selection screen D1. The plurality of candidates for the use include "temporary use" and "regular use". The user can select a use to be associated with the face information from among the plurality of candidates for the use displayed on the selection screen D1.

[0078] The decision button B1 is a button for determining the attributes and uses to be associated with the face information. The selection unit 661 determines the attributes and uses to be associated with the face information when the decision button B1 is operated by the user. Then, the selection unit 661 transmits, via the communication unit 61, the face information based on the face image G1 selected by the user and the attribute information and use information indicating the attributes and uses selected by the user to the lobby interphone 4.

[0079] As shown in FIG. 6, when a part of the face portion of the face image G1 is shielded by a shielding object such as a mask, the selection unit 661 of the present embodiment makes it impossible to select "regular use" as the use to be associated with the face information. For example, the selection unit 661 does not display "regular use" as one of the plurality of candidates for uses in the pull-down menu M2, or grays out the display of "regular use". The determination as to whether or not a part of the face portion of the face image G1 is shielded by a shielding object such as a mask is made by the quality determination unit 662.

[0080] The quality determination unit 662 determines whether or not the face image G1 selected by the user is suitable as a basis for the face information to be registered as authentication information. For example, the quality determination unit 662 performs pattern recognition processing on the face image G1 and extracts the face portion from the face image G1. Further, the quality determination unit 662 determines whether or not the orientation and size of the face portion are suitable as a basis for the face information, and whether or not a part of the face portion is shielded by a shielding object. The face image G1 determined by the quality determination unit 662 to be unsuitable as a basis for the face information cannot be used as a basis for the face information.

[0081] In the registration system 3 of the present embodiment, the portion of the face portion of the face image G1 determined by the quality determination unit 662 to be shielded by the shield is not a comparison target with the face image G1 when the authentication unit 475 of the lobby intercom 4 performs face authentication. In the example of FIG. 6, the portion of the face portion with dot hatching is determined by the quality determination unit 662 to be the portion shielded by the shield. For example, the registration unit 474 of the lobby intercom 4 uses only the portion of the face portion of the face image G1 that is not hatched as face information to be registered as authentication information.

[0082] The notification unit 663 performs notification regarding the permission level before the registration unit 474 of the lobby intercom 4 registers the face information as authentication information. For example, when the quality determination unit 662 determines that a part of the face portion of the face image G1 is shielded by a shield, the notification unit 663 notifies that the "permission level 2" cannot be associated because a part of the face portion is shielded by a shield. Specifically, the notification unit 663 causes a message such as "Since a part of the face is shielded by a shield, the 'permission level 2' cannot be associated" or "Since a part of the face is shielded by a shield, the 'regular use' cannot be associated" to be displayed on the selection screen D1. Note that the notification unit 663 may perform notification using a speaker or the like. By providing the notification unit 663 in the in-house master unit 6, the user can receive a notification regarding the permission level before the registration unit 474 of the lobby intercom 4 registers the face information as authentication information.

[0083] (3) Operations Next, the operations of the registration system 3 according to the present embodiment will be described with reference to FIGS. 7 to 9.

[0084] FIG. 7 is a sequence diagram showing the operation of the registration system 3 of the present embodiment. When a user such as an occupant of the dwelling unit 12 of the facility 1 performs a predetermined operation on the dwelling unit master unit 6, the dwelling unit master unit 6 receives an operation for registering face information based on the face image G1 as authentication information (S1: registration operation reception process). The dwelling unit master unit 6 transmits face information based on the face image G1 selected by the user, attribute information indicating the attribute selected by the user, and use information indicating the use selected by the user to the lobby intercom 4 based on the received operation (S2). When the lobby intercom 4 receives the face information, the attribute information, and the use information, it registers the permission level associated with the face information as authentication information based on these information (S3: registration process).

[0085] Note that the sequence diagram shown in FIG. 7 is merely an example, and the order of processing may be appropriately changed, or processing may be appropriately added or deleted.

[0086] Next, the operation of the dwelling unit master unit 6 of the present embodiment will be described with reference to FIG. 8. FIG. 8 is a flowchart showing the operation of the dwelling unit master unit 6 and corresponds to the registration operation reception process in step S1 of FIG. 7.

[0087] First, the dwelling unit master unit 6 (selection unit 661) receives the selection of the face image G1 by the user (S11). Next, the dwelling unit master unit 6 (quality determination unit 662) performs a quality determination on the face image G1 selected by the user and determines whether there is an obscuring object that obscures a part of the face portion of the face image G1 (S12).

[0088] When the dwelling unit master unit 6 (quality determination unit 662) determines that there is no obscuring object in the face image G1 (S12: No), the process proceeds to step S15. On the other hand, when the dwelling unit master unit 6 determines that there is an obscuring object in the face image G1 (S12: Yes), the dwelling unit master unit 6 (selection unit 661) excludes "regular use" from the uses that can be associated with the face information (S13). Further, the dwelling unit master unit 6 (notification unit 663) of the present embodiment notifies that the "permission level 2" cannot be associated with the face information as a notification process (S14).

[0089] Next, the residential main unit 6 (selection unit 661) determines whether or not the determination button B1 (see FIG. 5) has been operated by the user (S15). If the determination button B1 has not been operated by the user (S15: No), the residential main unit 6 repeats the process of step S15 while displaying the selection screen D1 on the display unit 63. On the other hand, if the determination button B1 has been operated by the user (S15: Yes), the residential main unit 6 transmits the face information based on the face image G1 selected by the user, and the attribute information and usage information regarding the attributes and usage selected by the user, to the lobby intercom 4 (S16). Then, the residential main unit 6 ends the registration operation reception process (S1 in FIG. 7).

[0090] Note that the flowchart shown in FIG. 8 is merely an example, and the order of processes may be changed as appropriate, or processes may be added or deleted as appropriate.

[0091] Next, the operation of the lobby intercom 4 of the present embodiment will be described with reference to FIG. 9. FIG. 9 is a flowchart showing the operation of the lobby intercom 4, and corresponds to the registration process of step S3 in FIG. 7.

[0092] First, the lobby intercom 4 (first acquisition unit 471 and second acquisition unit 472) acquires (receives) face information, attribute information, and usage information from the residential main unit 6 (S21). Next, the lobby intercom 4 (registration unit 474) confirms the attribute information (S22).

[0093] The lobby intercom 4 (registration unit 474) checks the attribute information to determine whether the attribute is "visitor" (either "regular visitor" or "irregular visitor") (S23). If the attribute is "visitor" (S23: Yes), the lobby intercom 4 associates "permission level 1" (the permission level that allows entry into facility 1 even when a part of the face of person H1 is blocked) with the face information (S24). Then, the lobby intercom 4 associates the attribute information and usage information indicating the attribute and usage selected by the user with the permission level in the face information, and registers the face information as authentication information (stores it in the storage unit 46) (S27). Then, the lobby intercom 4 ends the registration process.

[0094] On the other hand, in the process of step S23, if the attribute is not "visitor" (S23: No), the lobby intercom 4 (registration unit 474) checks the received usage information to determine whether the usage is "temporary usage" (S25). If the usage is "temporary usage" (S25: Yes), the process proceeds to step S24 and subsequent steps. If the usage is not "temporary usage" (S25: No), the lobby intercom 4 (registration unit 474) associates "permission level 2" with the face information (S26). Then, the process proceeds to step S27.

[0095] Note that the flowchart shown in FIG. 9 is merely an example, and the order of processes may be changed as appropriate, or processes may be added or deleted as appropriate.

[0096] (4) Modification Example The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved.

[0097] In addition, functions equivalent to those of the registration system 3 according to the above embodiment may be embodied in a registration method, a (computer) program, a non-transitory recording medium storing the program, or the like. A registration method according to one aspect is a registration method for registering authentication information for determining whether to permit entry into the facility 1. The registration method includes a first acquisition step, a second acquisition step, and a registration step. In the first acquisition step, face information based on a face image G1 including the face of person H1 is acquired. In the second acquisition step, attribute information regarding the attributes of person H1 in the facility 1 is acquired. In the registration step, a permission level based on the attributes of person H1 is associated with the face information, and the face information is registered as authentication information for determining whether to permit entry into the facility 1. A program according to one aspect is a program for causing one or more processors to execute the above registration method.

[0098] The execution entity of the registration system 3 or the registration method in the present disclosure includes a computer system. The computer system mainly consists of a processor and a memory as hardware. By the processor executing a program recorded in the memory of the computer system, the function as the execution entity of the registration system 3 or the registration method in the present disclosure is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunication line, or may be provided by being recorded on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Here, integrated circuits such as the IC or LSI mentioned here have different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, for an FPGA (Field-Programmable Gate Array) that is programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit sections inside the LSI, it can also be adopted as a processor. The plurality of electronic circuits may be integrated on one chip, or may be provided dispersedly on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided dispersedly in a plurality of devices. The computer system mentioned here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0099] It is not an essential configuration for the registration system 3 that at least some functions of the lobby intercom 4 are integrated in one housing, and at least some functions of the lobby intercom 4 may be provided in a distributed manner in a plurality of housings. For example, at least some functions of the lobby intercom 4 may be provided in the resident master unit 6, the management room unit 8, a server, or the like.

[0100] It is not an essential configuration for the registration system 3 that at least some functions of the resident master unit 6 are integrated in one housing, and at least some functions of the resident master unit 6 may be provided in a distributed manner in a plurality of housings. For example, at least some functions of the resident master unit 6 may be provided in the lobby intercom 4, the management room unit 8, or a server.

[0101] Conversely, in the above embodiment, at least some functions of the registration system 3 that are distributed among a plurality of devices may be integrated in one housing. For example, some functions of the registration system 3 that are distributed between the lobby intercom 4 and the resident master unit 6 may be integrated in one housing.

[0102] An imaging unit different from the imaging unit 42 may capture the face image G1. The third acquisition unit 473 may acquire the face image G1 as a face image G1 captured by an imaging unit different from the imaging unit 42. Another imaging unit is, for example, a surveillance camera or the like installed in the lobby 11 that captures a person H1 visiting the lobby 11.

[0103] In the above embodiment, the case where the permission levels include two permission levels of "permission level 1" and "permission level 2" is exemplified, but there may be three or more permission levels.

[0104] The authentication unit 475 may vary the threshold value at the time of face authentication according to the permission level associated with the authentication information. For example, the threshold value of the similarity between the authentication information associated with "permission level 1" and the face portion may be a value lower than the threshold value of the similarity between the authentication information associated with "permission level 2" and the face portion.

[0105] When the face image G1 acquired by the third acquisition unit 473 is an image in which the entire face of the person H1 is blocked, the authentication unit 475 may not permit the person H1 to enter the facility 1 without determining the permission level.

[0106] In the above embodiment, the case where the registration unit 474 registers the face information in association with the "permission level 1" when the attribute information is information indicating "visitor" is illustrated. However, when the attribute information is information indicating "regular visitor", the registration unit 474 may associate the "permission level 2".

[0107] (Summary) As described above, the registration system (3) according to the first aspect is a registration system (3) for registering authentication information for determining whether to permit entry into the facility (1). The registration system (3) includes a first acquisition unit (471), a second acquisition unit (472), and a registration unit (474). The first acquisition unit (471) acquires face information based on a face image (G1) including the face of the person (H1). The second acquisition unit (472) acquires attribute information regarding the attribute of the person (H1) in the facility (1). The registration unit (474) associates a permission level based on the attribute of the person (H1) with the face information and registers the face information as authentication information for determining whether to permit entry into the facility (1).

[0108] According to this aspect, the permission level based on the attribute of the person (H1) can be associated with the face information and registered as authentication information. For example, when the attribute of the person (H1) is "visitor", a permission level that permits entry into the facility (1) even when a part of the face of the person (H1) is blocked by a shielding object such as a mask is associated with the face information of the visitor and registered as authentication information. Therefore, for example, when registering the authentication information of the visitor to the facility (1), it is not necessary for the visitor to remove a shielding object such as a mask, so that the registration of the authentication information can be facilitated.

[0109] In the registration system (3) according to the second aspect, in the first aspect, there are a plurality of permission levels. The registration unit (474) can associate a plurality of permission levels with the face information for each attribute of the person (H1).

[0110] According to this aspect, since it is possible to associate a plurality of permission levels with the face information for each attribute of the person (H1), the convenience for the person (H1) using the facility (1) can be improved.

[0111] In the registration system (3) according to the third aspect, in the first or second aspect, the registration unit (474) associates use information indicating a use corresponding to the permission level with the face information.

[0112] According to this aspect, since it is possible to associate use information corresponding to the permission level with the face information, the security robustness can be maintained.

[0113] In the registration system (3) according to the fourth aspect, in the third aspect, the use includes at least one of a temporary use and a regular use.

[0114] According to this aspect, for example, by associating use information indicating "temporary use" with the face information associated with a permission level lower than a predetermined standard, restrictions are imposed on the authentication information, and the security robustness can be maintained.

[0115] In the registration system (3) according to the fifth aspect, in any of the first to fourth aspects, when the attribute of the person (H1) is a visitor to the facility (1), the registration unit (474) registers the face information as authentication information at a permission level that allows entry into the facility (1) even when a part of the face of the person (H1) is shielded.

[0116] According to this aspect, when registering the authentication information for a visitor, since it is not necessary for the visitor to remove a shielding object such as a mask, the registration of the authentication information can be facilitated.

[0117] In the registration system (3) according to the sixth aspect, in any of the first to fifth aspects, the second acquisition unit (472) acquires attribute information from an information terminal provided in the facility (1).

[0118] According to this aspect, since the second acquisition unit (472) acquires attribute information from an information terminal provided in the facility (1), for example, when the information terminal is a main unit of a residential unit, the registration system (3) can acquire, for example, the attribute information (associated with the face information) selected by the resident of the facility (1).

[0119] In the registration system (3) according to the seventh aspect, in any of the first to sixth aspects, the first acquisition unit (471) acquires face information via an information terminal provided in the facility (1).

[0120] According to this aspect, since the first acquisition unit (471) acquires face information via an information terminal provided in the facility (1), for example, when the information terminal is a main unit of a residential unit, the registration system (3) can acquire, for example, the face information selected by the resident of the facility (1).

[0121] The registration system (3) according to the eighth aspect further includes a notification unit (663) in any of the first to seventh aspects. The notification unit (663) performs notification regarding the permission level before the registration unit (474) registers the face information as authentication information.

[0122] According to this aspect, the user can receive notification regarding the permission level before the registration unit (474) registers the face information as authentication information.

[0123] The registration system (3) according to the ninth aspect further includes, in the second aspect, a third acquisition unit (473) and an authentication unit (475). The third acquisition unit (473) acquires a face image (G1). The authentication unit (475) determines whether to permit the person (H1) to enter the facility (1) based on the face image (G1) acquired by the third acquisition unit (473) and the authentication information. When a plurality of permission levels are associated with the face information for each attribute, the authentication unit (475) determines one permission level from among the plurality of permission levels based on the face image (G1) acquired by the third acquisition unit (473), and performs face authentication using the face information associated with the one permission level.

[0124] According to this aspect, for example, when a part of the face of the person (H1) is blocked, the authentication unit (475) does not perform face authentication using face information associated with a permission level that does not permit entry into the facility (1) when a part of the face of the person (H1) is blocked, thereby reducing the processing load on the authentication unit (475).

[0125] In the registration system (3) according to the tenth aspect, in the ninth aspect, when the face image (G1) acquired by the third acquisition unit (473) is an image in which at least a part of the face of the person (H1) is blocked, the authentication unit (475) determines a permission level that permits entry into the facility (1) even when a part of the face of the person (H1) is blocked as the one permission level.

[0126] According to this aspect, when a part of the face of the person (H1) is blocked, the authentication unit (475) performs face authentication using face information associated with a permission level that permits entry into the facility (1) even when a part of the face of the person (H1) is blocked, thereby reducing the processing load on the authentication unit (475).

[0127] In the registration system (3) according to the eleventh aspect, in the second aspect, the number of permission levels that the registration unit (474) can associate with the face information differs according to the attribute of the person (H1).

[0128] According to this aspect, since the number of permission levels that the registration unit (474) can associate with the face information differs according to the attributes of the person (H1), the authentication information can be registered in a manner suitable for each attribute.

[0129] Regarding the configuration other than the first aspect, it is not an essential configuration of the registration system (3) and can be appropriately omitted.

[0130] The registration method according to the twelfth aspect is a registration method for registering authentication information for determining whether to permit entry into the facility (1). The registration method includes a first acquisition step, a second acquisition step, and a registration step. In the first acquisition step, face information based on a face image (G1) including the face of the person (H1) is acquired. In the second acquisition step, attribute information regarding the attributes of the person (H1) in the facility (1) is acquired. In the registration step, a permission level based on the attributes of the person (H1) is associated with the face information, and the face information is registered as authentication information for determining whether to permit entry into the facility (1).

[0131] According to this aspect, a permission level based on the attributes of the person (H1) can be associated with the face information and registered as authentication information. For example, when the attribute of the person (H1) is "visitor", a permission level that permits entry into the facility (1) even when a part of the face of the person (H1) is covered by a shielding object such as a mask is associated with the face information of the visitor and registered as authentication information. Therefore, for example, when registering the authentication information of a visitor to the facility (1), it is not necessary for the visitor to remove a shielding object such as a mask, so the registration of the authentication information can be facilitated.

[0132] The program according to the thirteenth aspect is a program for causing one or more processors to execute the registration method according to the twelfth aspect.

[0133] According to this aspect, a permission level based on the attributes of a person (H1) can be associated with face information and registered as authentication information. For example, when the attribute of the person (H1) is "visitor", a permission level that allows entry to the facility (1) even when a part of the person's (H1) face is covered by a shielding object such as a mask is associated with the face information of the visitor and registered as authentication information. Therefore, when registering the authentication information of a visitor to the facility (1), for example, it is not necessary for the visitor to remove a shielding object such as a mask, so the registration of the authentication information can be facilitated.
